Connecting to Lines
to be Measured
Chapter 3
• Voltage cords or Clamp sensors should only be connected
to the secondary side of a breaker, so the breaker can pre-
vent an accident if a short circuit occurs. Connections
should never be made to the primary side of a breaker,
because unrestricted current flow could cause a serious
accident if a short circuit occurs.
• Connect the clamp-on sensors or voltage cords to the
instrument first, and then to the active lines to be measured.
Observe the following to avoid electric shock and short cir-
cuits.
(1) Do not allow the voltage cord clips to touch two wires at
the same time. Never touch the edge of the metal clips.
(2) When the clamp sensor is opened, do not allow the metal
part of the clamp to touch any exposed metal, or to short
between two lines, and do not use over bare conductors.
• To prevent electrical shock and personnel injury, do not
touch any input terminals on the VT (PT), CT or the instru-
ment when they are in operation.
• The maximum rated voltage between terminals is 1000V AC.
Attempting to measure voltage in excess of the maximum
input could destroy the instrument and result in personal
injury or death.
• The maximum rated voltage between input terminals and
the ground is as follows;
(CAT III) 600 V AC, (CAT IV) 300 V AC
Attempting to measure voltages exceeding this level with
respect to ground could damage the instrument and result
in personal injury.
